To all whom t may concern.'-

Be it known that' I, ABRAHAM T; H. BROWER, a citizen of the United States, and

' a resident of Chicago, county of Cook, and

lState of Illinois, have invented certain new in Printing- Presses, of which the following is a full, clear, and exact description.

The invention relates to printing presses and more particularly to proof presses employing a' 'reciprocating 'type bed and a paper carrying cylinder gearedto the bed to effect the forward printing and returning movementsy of the bed as thecylinder is rotated in opposite directions. The invention seeks to provide improved means 'for mounting the cylinder and for raising and lowering 'the same'to and from the bed, so that the tympan will not contact with 'the type surface upon the return movements of the bedand cylinder. lThe invention also i seeks to provide improved 'means for arresting forward and return movements of the bed and cylinder without shock.

The invention consists in the features of improvement hereinafter set forth, illusl trated in the 4 preferred form in the accom- 'panying drawings and more particularly pointed out in the appended claims.

"In the draw-ings, Figure 1 is a side elevation .of the improved press with one end of the frame and the lower portion of the base broken away, and with parts shown in secr tion on the linefl--l of Fig. 2. Fig. 21 is I acrosssection on theline 2-2 of'Fig. 1. Fig. 3 1s a partial 'cross-section on the line 3--3 of Fig. 1. Figs. ,4, 5 and 6 are detail sections on the linesyl-l, 5-5 and 6-'6,

respectively of Fig.v 2. Figs. 7 and 8 are detail sections on the lines 7-7 andv 8- -8,v

respectively', of Fig.2. c Thehorizontal frame 10 of the press is mounted on and is securely bolted to a suitable supporting standard or vbase 11.

These parts are' formed of cast iron and the frame 10 1s strengthened at intervals by transverse webs 12. At its upper portion the frame 10 is provided 'with guides 13 The for the reciprocating type bed 14. latter is provided on its under side with longitudinally extending guide Iribs 15 near its edges and with a central, longitudinal bearing rib 16, and 'also {with} transverse strengthening ribs 17. The ribs' 15 and portionsjl'of the ,frame'are providedwith guidey grooves 18 which form lrace-ways for of the guide 13 on opposite sides ofthe groove 18 therein. The central portions of the guide grooves, as shown most clearly in Figs. 2 and 3, are cylindrical and are of the same radius as the bearing balls 19. 'These cylindrical central portions of the grooves preferably extend through arcs of about 90 and the flaring side portions of the grooves are tangent lto the central cylindrical portions thereof and Ito the bearing balls.

The endsof the rspacer bars 20 are provided Withstop blocks 21 which, at the ends of the movement of the bed, are arranged to engage stop pieces 22 (see Fig. 1) fixed to the ends of the frame 10, so that the sets of bearing balls are maintained in proper'- position relatively togthe reciprocating 'type bed. IPreferably, the stop pieces 22 are covered with raw hide, leather or the like.

To'relieve the ball bearings in partfrom the pressure of the cylinder upon the bed, the central bearing ribI 16 of the latter is arranged to lengagey a supporting wheel 23. This wheel is mounted upon'a short crossshaft 24 that is'journaled at its ends in tlie upright side'portions of a bracket '25. This bracket is bolted to 'the upper portion` of the base 11 between-a pair of lugs 26 thereon. lShims.271areinterposed between the upper part.y of the base and the-bracket 25 to take up any play between the` guiding and supporting Wheel 23 Vand the longitudinal rib 16 of the bed.

The supportingand guiding wheel is arranged invertical alinement withthe axis .of the cylinder 28 'which is supported above the bed by a pair of heavy brackets l29. The

sets of bolts 30. Preferably, as shown in Fig. 2, the cylinder.'bracketsl are provided with lips`29 which overlap the upper'and lower edges of the framelO. v The ends of the cast iron cylinder 28' are provided with hubs 28" ('s'ee `Fig`s.`3 and 5) which are keyed to a shaft 31. Each en d ofthe shaft is journaled'in av bush or bearing 32 and these" bearings are arranged between the upper ends of the cylinder brackets and cap pieces 33 which are'secured to the brackets by bolts 34. The projectingends of the shaft are provided with hand wheels 35, so

that the cylinder may be rotated from either side of the press.

The surface of the cylinder is recessed 1n the usual manner throughut the greater portion of its length to receive the tympan and at its ends is provided with bearing flanges 36 which engage the bearers 37 fixed Vin the usual manner to the sides of the type bed. A gearwheel 38 is fixed to one end of the cylinder by screws 39 'and meshes with a rack 40 fixed'to one'of the side edges of the bed to thereby effect the forward and back movements of the latter as the cylinder is rotated in opposite directions. The cylinder isv provided at its opposite end and adjacent its periphery with a laterally pro-- jecting stud 41 which is arranged to cooperate with a reciprocating or oscillating stop device on the frame of thelmachine to limit the movements `of the cylinder and the bed. Preferably, the studl 41 is provided with an anti-friction roller 42 which, at the` opposite ends of the movement ofthe cylinder, is arranged to engage -with` one or the other of two notches or seats 43 frmed in a segmental oscillating stop device 44. This stop device is pivotally mounted on the inner face of the lft hand cylinder bracket by a stud 45. A spring 46 is coiled' about the hub of' the stop device 44. One end of,`

the spring is l.connected tothe central portion of the stop device and its other end is arranged between a pair ofA lugs 47 formed upon the inner face of the cylinder bracket.

Beneath the stop device, the cylinder bracket is provided with inwardly projecting abut` ments or ledges 48 which are covered with a strip 49 of `rawhide, -leather or the like and against which the ends of the 'stop de-. yvice'strike when it is shifted in one or the other direction by the engagement of the cylinder stop roller therewith. When the cylinder is shifted in forward directionlindicated by the arrow in Fig. 7), the stop rller 42 thereon passes out of one ofthe seats 43 and the spring 46 then holds'the stop device 44 in central position, so that at the end of the forward movement, the

stop` roller engages `the other notch or seat 43 and shifts the stop device until its movement is arrested by its enga-gement with the rawhide strip covering one of the abutments 48. The stop device thus serves to yieldingly arrest the, forward lmovementof the bed and cylinder withoutshock o r jar and in a similar manner arrests the return movement of these parts.

The cylinder shaft bearings 32 are provid-ed with eccentric portions 50 (see Figs. 1, 3, -7 and: 8)k which are free to oscillate in suitable seats to thereby lower and raise the cylinder upon the forWa-rdand return movements of the bed. Preferably, these eccentrics are fitted within outer eccentrics 51 and the` latter infturnlare arranged in -seats formed in the upper ends of the brackets 29 and in the bracket cap pieces 33. 'llhe outer eccentrics are shifted only when it is desired to adjust the ycylinder to bring its tympan surface and flanges 36in proper relation to the type \bed and the bearers 37 thereon. For convenience in adjusting the eccentrics 51, they are provided with a series of radial holes 52. `These outer `eccentrics can only be shifted Vby vremoving the,

cap pieces 33 and, once they are properly 'set, they are securely clamped in place and so held against movement by the cappieces which, in turn, are held in position by the bolts 34. Each of the inner eccentrics or shaft bearings is provided with a flange 53 4which overlaps the inner face of the outer eccentric' 51 and also abuts against the innerv faces of -the cylinder'v bracket 29 and thebracket cap 33. A plate 54 similar in size to the-flange 53 overlaps the outer faces o f these parts and is connected to the main body of` the inner eccentric bearing by plate A54 which is fastened to the adjacentA bearing. The crank arm 57 vls arranged inside the right hand bracket 29 and is formed in piece lwith the main body of the right hand bearing '32 (see Figs. 1 and 4'). The ends of these crank arms are forkedand are connected to the upper ends of a pair of links 58. The lower ends of these links are connectedto the forked ends of a pair" 0f shiftulevers` 59 and '6 0. These Shifters or levers extend beneath the cylinder bearings and 'are"m ounted', at their forward ends, upon a" common transverse rock shaft 61 that is journaled in the cylinder.l brackets 1129., The shift levers 59 and 60 are both keyed to the shaft 61 so that they. are moved together to thereby oscillate the eccentric shaft bearings 50 to raise and lower ythe cylinder.

The shift of the levers, 59 and 60 is controlled by a double-path cam mounted on one -end of the cylinder. Preferably, this cam .is formed in piece with the gear 38, the outer face of which is provided with inner and outer cam grooves 62and 63 willich are separated by a rib 64 except at the portion of the cam which is lowermost when the bed ico and cylinder are at the ends of their moveposition' shown in Fig ment. At this portion, the ends ofthe outer cam groove 63 are curvedv inwardly and merge into the inner cam groove 62. These cam grooves coperate with a stud 65 onthe adjacent shift lever 60 and which stud is preferably provided with an anti-friction roller 66 extending within the grooves. Onel end of the inner groove T62 is normally closed by a gate 67 which is pivotally connected to the cam by a screw 68 and which is held inlnormal position by a V-shaped spring 69 (see Figs. `1, 3 and 4). This spring is arranged in a recess in the yinner face of the gate and its ends respectively engage the gate and the cam body. The'tendency of thearms of this V-shaped spring to spread apart 'holds lth gate in the normal and in full lines in Fig. 4. When the paper carrying cylinder and type bed vare in the initial position shown in the drawin s, the roller 66 on the shift'lever 60 is in t e position shown and the cylinder is in-its lowermostprosition with l the flanges y36 thereof engaging the bearers 37of the type bed. Upon the forward movement o-f the cylinder in the directionv indi,-h cated by the arrows in Figs. 1, 4 and 8,'the roller 66 on the shift lever entersgthe open end of theinner cam groove 62 andis maintained in this groove to hold the'cylinder in engagement with the type bed until the cylinder has corripleted )a full revolution which constitutes this' forward movement.

vAs the cylinder approaches the end of its forward movement, the roller engages the rearinclined edge of the gate67 and swings it about its pivot against the tension ofthe spring 69,`so that the roller can pass the gate and again occupy 'the position shownl in Figs. 1 and 4. On the reverse or return movement of the cylinder, the roller 66y engages the end of the gate and is guided thereby into the outercam groove 63', so that the shift levers 59 and 60 are depressed and,

throu h the ned-iumjof the links 58, oscillate t e eccentric.- shaft bearings 50, andv thereby the cylinder is 'raisedfdurin'g the return movement ofthe bed "and cylinder. At lthe end of the return revolution ofthe cylinder, the roller 66) and the shift levers 59 and 60 controlled therebyvv are returnedto the positionshown and the cylinder is again lowered' into engagement .with the bed. In this way, the cylinder isj held in lowered position during the forward -or printing,

" `strokeof the bed and cylinder and is automatically raised to clear the *type surface on the return movement of these parts. The

' Vertical shift of the cylinder effected-by the eccentrics .50 is slight, but is sufficient-,to raise the tympan on the cylinderclear ofthe type surfacedu'rin the return movements ofthe cylinder an Vvbed.`\-v This slight shift is not suficient` to disturb the proper meshing of the cyl/inderjgear 38 with the bed rack 40. During the forward movement of the bed L and cylinder, the center of the cylinder shaft 31 is vertically in line and below the centers tween it and the bed, sinceany such adjust- 7 ment is effected by means of the outer eccentrics 51. As stated, the outer eccentrics 'when once adjusted, are clamped against movement bythe bracket caps 33. The cylinder is provided, as usual, on one,

side -with an opening and one ofthe edge walls of this opening has a series of pins 70 which-coperate with a series of clamps 71 for securing one lend of the tympan to the cylinder. The tympan clamps are mounted upon a cross-shaft or rod 72 'arranged with- "in the cylinder. and journaled in the ends thereof. At one end and outside ofthe cylinder,

or lever -73 which normally engages a lug 74 on the end of the cylinder to hold the tym lpan clamps inA position. r1`he arm 73 lis formed `of spring steel, so that it may be shifted laterally into and out` of engagement with the lug 74 to release and secure the tympan. Thevo'ppositel ends of the blankets forming the tympan pass around a pair of toothed reel rods 75 journaled within the cylinder adjacent the opposite edge of the opening thereof. These rods are provided with square shanks 76 (see Fig. 7) which project beyond. one end of the cylinder for receiving'l kets may be drawn tightly around the cylinder; Ratchets of the reel rods.

i A series of lgrippers 80 forholding the leading edge of thel paper against the tympan 'are mountedupon a rod,81 which is journaled in the ends of the cylinder and is arranged,A as shown, cylinder opening. A crank arm 82 on one end f the rod or shaft 81 is connected to the hooked end ofja sliding bolt 83. The 1 latter is arranged to slide and also oscillate to. a slight extent through a stud ,'84 xed 'to the inner face 4of the left hand end'of the `cylinder. A spring 85, coiled about this rod, extends between the washers86 that 'abut' respectively against the stud 84 and' i 78 and coperating spring-held pawls1 7 9 prevent the unwinding movement this shaft is provided with an arm suitable tools by which the blan- 1].0- near the edg'eof the,l

against a nut 87 ixedato the end'ofthebolt,

so vthat the tension of the spring is exerted .to holdthe grippers 80` againstthe leading edge of theftymp'an. The left hand endy of 'the gripper shaft vor rod 81 outside of the vend of the cylinder is provided with a handle' 88'by which the grippers may ,be oscillated andshifted to'disengaged position. In

thisl disengaged.position, the outer curved end of the spring bolt 83 hooks over the shaft or rod so that thef'spring 85 then acts to hold the grippers away from the' cylinder. The grippers are only shifted to. this extreme disengaged position when it is desired to adjust the tympan, but inasmuch as .the gripper spring is'thusarranged to shift on opposite sides'of'afcentral position,

it will Iact to yieldingly'-hold the grippers both in normal and in disengaged position.

Means is provided for shifting the grippers slightly to release the leading edge of the paper, and is so arranged that the grippers may be released by hand or automatically. A shaft 89 extends in front of the cylinderandis` journaled at its ends in the cylinder bracketsv29. An eccentric camv90 (see Figs. v2, 5 and 8) is fixed to the left hand vend of this shaft. `The edge of this eccentric cam engages the outer. curved edge 20 portion at 'the upper end of an intervening arm or trip device 91 and which arm is pivf otally mounted at its lower end on a crossend of the'machine wit-h a handle 96 (see rod 92 extending between the cylinder brackets. f The intervening armor releasing trip y1s provided at its upper end and on its inner vedge with an inclined cam face 93 which is .arranged lto coperate with aroller, 94 on theend of an arm 95 which is fixed to the left Ahand end of the gripper shaft or rod 81. The yshaft 89 is provided at the left hand Figs. Zand 8) and at the opposite end of the `machine (see Figs. land 2) it is provided V- st l ward the notched hub' 98 by a spring 100,

.with a handle 97, having an enlarged n otched hub 98. A dog 99 pivoted on the right hand Aend of the rod 92 is pressed )towhich extends between the dog and the lug l0 0. onthe outer face of the right hand cylinder bracket. The movement of the ec- Avcentric cam 90 r'and intervening arm 91 is limited in; one direction by the engagement of the curved outer end of the handle 97 with the edge of the' cylinder bracket 29.'

In the opposite direction, the movement of these parts is limited by the engagement of a toe-piece 101 on the'pivoted end-of thevintervening arm or releasing trip 91 with a against -th'e tension of the spring 85 and 'projecting lug 102 on the inner face lof the left hand cylinder bracket.

With the low-part of the eccentriccam 90 in engagement with the intervening arm cr releasing trip, the roller 94'will clear the lnclined cam face 93 at the upper end ofthe arm, so that the grippers will not be automatically released, but, inthe initial posi-v tion of the cylinder, the shaft 89 can be ro tated from either side of the machine by means of eitherof the handles 96 6r 97 and the upper. end of the arm 91 forced againstthe .roller 94 to' rock the" gripper shaft 81 therebyf release the grippers., The paper maythen be placed in position- 'on the cylinder w1th its front edge againstthe guides side.

provided therefor and then, by releasing the eccentric cam 90, the spring 85'will shift lthe grippers to engage the paper.

vlf desired, the eccentric cam 90 can be I heldin shifted position by means of the dog 99 on the right hand side of the machine,

lso thatthe grippers willbe automatically released at the end of the forwardmovement of the cylindervand will be automatically returned to position'to grip .the paper after the cylinder is moved forward to'disengage the roller 94 Vfrom the inclined 'cam face 93 of the intervening arm or trip vdevice 91. rlhe hub'i98 with which the dog 99 coperates, is provided with a number of notches so thatthe dog serves to hold the cam 90 and the 'trip armin anyone of a number of diiierent positions. In theposition shown the grippers are released byhand. ln the other positions the grippers are automatically released` andy restored at different points. The end of the dog and the notches of the hub-are provided with'oppositely inclined faces so that the shaft 89 and cam 90 and extend around the edge of the cylinder opening. This rod is journaled in the ends of the cylinder vand at its left hand end has an arm 105 fixed thereto. A cushion spring 106 extends between the end of this arm and the .end ofl an arm 107 which is loosely i mounted `on the rod 104 and is pressed by the y.spring 106 against" they outer ,cylinder wall. Preferably, as shown, the front guide :fingers 103 are provided atpointsin line with the surface ofc the tympan with shoulders 103 to aid Ain accurately positioning the paper on the cylinder.

emr

It should be noted that the outer face of the cylinder adjacent the edge of the cylinvder opening is cut away, so that the paper grippers lie within the periphery of the cylinder bearing flanges 36 and'will, therefore, clear the surface of the type and chase upon .the bed 14, vand means are provided for shifting the front guides 103 to also clear all portions of the type surface. For this purpose, the front guiderod or shaft v104 is provided on its left hand end with an arm 108 (see Fig. 7 having a roller 109 on its end. As the cylinder is rotated, and as the' guide fingers approach the type surface, the roller 109 engages a fixed curved cam ledge 110 which is secured to the inner face of the left hand cylinder bracket by studs 111 (see Figs. 2 and 7 In this manner, the, front 130 portions of any type-high chase on the bedguide fingers are automatically withdrawn into the cylinder to clear the type and all during both the forward and baclr movement of the bed and cylinder. l

A sleeve 112 ts over the rock shaft v89 and interlockswith a part 112 on the right f hand cylinder bracket so that 4it is held against movement.A The shaft 89, however, is free to rock within this sleeve. A series of brackets-or collars 113 are fixed to the sleeve 112 and a series of sheet guiding bands 114 are fixed at the upper ends to in engagement with the type bed until it has.

lof the cylinder fin forward direction, the

these brackets or collars. Intermediate their ends, the sheet Aguiding bands are provided with .'\doubled, offset `portions 115 lwhich are vriveted together andthe outer looped ends of which encircle the transverse rod 92.

In operation, the 1paper `sheet is placed on the cylinder with its leading edge engagingA the guide fingers 103 and the shoulders 103 thereof, so that it will be engaged `by the grippers 80. If necessary, thegrippers are shifted by means of the camf on the shaft 89 and the'intermediate arm 91, as dewill automatically release the fingers.. Asv

above described, the intermediate arm .91 may be held in such position that inthe normal position 'of thecylinder, the grippers will be held released; but lwill engage the forward edge of the (paper as soon as the initial movement of the cylinder disengages' the roller 94 from the inclined cam face 93- of the arm. The cylinder is then rotated by one of the handles 35 to shift the bed and carry the paper on the cylinder into engagement with the type .on the bed. During this forward movement, as previously de` scribed, the roller 66 passes through the in-v ner grooves 62 of the double-path cam on the cylinder, so that the latter isfmaintained completed a full revolution in forward'di'- rection. Atthe end of. a single revolution 80 arel released, either by hand or automatically, as described, and the paper is removed from the cylinder. The cylinder is then rotated `in the opposite direction to ini` tial position. roller 66 is guided by the gate 67 into the grippers outer groove ofthe double-path cam and the cylinder is raised by oscillating the eccentric shaft bearings 50 through the medium of the levers 59 and 60 and links 58., The movement of the cylinder'and bed in opposite di rections is limited by a stop device 44, as already described. I C v l The grippers During this movement, the
